Abstract

A cap is described for closing a liquid beverage container for allowing the beverage to be sucked out of the container through a spout, while preventing spillage when no suction takes place. A demand valve is incorporated into the cap, which has an inlet port communicating with the interior of the container, a discharge port communicating with the spout and a control port communicating with the ambient atmosphere through a hole in the cap. The valve has a valve seat and a closure element controlling the flow from the inlet port to the discharge port urged to move into an opening position in dependence on the excess of the control pressures over that in the discharge ports, this movement being in the direction opposed to the flow and urged by the pressure in the container in a direction to seal against the valve seat. In the invention, the demand valve is formed by two members that are mounted on the inner surface of the cap. The first member is rigid and defines the valve inlet port and the valve seat. The second member incorporates the valve closure element and a resilient membrane which includes the valve closure element and serves as a pressure sensitive diaphragm. The second member also seals against the first member, around the hole in the cap and around the spout.

Description

本発明は、液漏れを防止する飲料容器用の蓋に関し、飲料容器に取り外し可能にまたは永久に係合した場合の、蓋に関するものである。   The present invention relates to a lid for a beverage container that prevents liquid leakage, and relates to a lid when removably or permanently engaged with a beverage container.

幼児や虚弱者に使用されるような、液漏れを防止するカップに対する必要性は周知である。これらのカップは液体密閉で好適には空気密閉であり、カップが子供により傾けられたり逆さにされた場合、あるいは横に倒されたり、ひっくり返されたりした場合にも液漏れしないように設計されている。子供がカップを不注意に持ち歩く場合に起きる、横に振られたり、振り回されたりした場合にも好適には液漏れしないことが求められている。   The need for a cup that prevents liquid leakage, such as that used by infants and the weak, is well known. These cups are liquid-tight and preferably air-tight and are designed to prevent liquid leakage when the cup is tilted or inverted by a child, or is laid down or turned over. Yes. It is required that the liquid does not leak suitably even when the child is swung sideways or swung, which occurs when the child carelessly carries the cup.

この目的のため幾つかの既知の設計がある。第１の設計ではカップを密閉および／または開封するのに注意深い動作が必要とされ、このようなカップは幼児に密閉を任せられない点で明らかに不利である。第２の設計は飲み口での減圧に対応して自動的に開き、吸引が終了すると再密封するように意図された圧力操作弁を有する。このような弁は容器内の高圧と飲み口での低圧とを識別できないという一般的な問題を有する。従ってこのような弁は液漏れの防止が効率的でないか、吸引に望まないレベルの抵抗を有するかのいずれかである。   There are several known designs for this purpose. The first design requires a careful action to seal and / or open the cup, and such a cup is clearly disadvantageous in that it cannot be entrusted to the infant. The second design has a pressure-operated valve that opens automatically in response to a vacuum at the mouth, and is intended to reseal when suction is complete. Such a valve has the general problem that it cannot distinguish between the high pressure in the container and the low pressure at the mouth. Thus, such valves are either not efficient at preventing leakage or have an undesired level of resistance to suction.

圧力操作弁を有するカップのさらなる問題は、それが炭酸飲料あるいは温飲料に対し安全に使用できないことである。後者の場合、カップが逆さになると、出口は液体によって覆われているので液体が空間の空気を熱し容器内の圧力を増加させ、その後液体を放出する。   A further problem with cups with pressure operated valves is that they cannot be safely used for carbonated or hot beverages. In the latter case, when the cup is turned upside down, the outlet is covered with liquid, so the liquid heats the air in the space, increasing the pressure in the container and then releasing the liquid.

上記の不利な点を避けるため本発明では、自己密閉式デマンド弁として既知の弁を使用している。自己密閉とは容器内部の圧力が弁を開放するよりはむしろ閉鎖するように作動するところから来ている。このような弁の更なる利点は弁が非常に低い吸引圧で開けられるように設計可能であることである。   In order to avoid the above disadvantages, the present invention uses a known valve as a self-sealing demand valve. Self-sealing comes from the fact that the pressure inside the container operates to close rather than open the valve. A further advantage of such a valve is that the valve can be designed to be opened with very low suction pressure.

自己密閉式デマンド弁を実現する単純で一般的な方法は、弁の開放時に弁閉鎖部位が液流方向と反対に作動するように弁を組み立てることである。この種の弁の例は特許文献１、特許文献２および特許文献３に記載されている。
弁は１つのダイアフラムを有し、それは第１の側では一定圧、一般には大気圧を受け、第２の側で弁閉鎖部位に作用する。弁閉鎖部位は弁シートに対し密閉する閉鎖位置に偏っている。カップの出口側の圧力はダイアフラムの第２の側に作用し、飲み口で吸引が行われたときに、ダイアフラムは、弁閉鎖部位を弁シートから乖離させる方向に持ち上げ、弁を開放する。飲み口で吸引が行われないときは、弁閉鎖部位の偏移した力は弁閉鎖部位を閉鎖位置に戻し、閉鎖を維持し、そして弁入口の正の圧力はいずれも閉鎖する力を増大させる。 A simple and common way to realize a self-sealing demand valve is to assemble the valve so that when the valve is opened, the valve closing site operates in the opposite direction of the liquid flow. Examples of this type of valve are described in Patent Document 1, Patent Document 2, and Patent Document 3.
The valve has one diaphragm, which receives a constant pressure, generally atmospheric pressure, on the first side and acts on the valve closure site on the second side. The valve closing portion is biased to a closed position that seals against the valve seat. The pressure on the outlet side of the cup acts on the second side of the diaphragm, and when suction is performed at the drinking mouth, the diaphragm lifts the valve closing portion in a direction to separate from the valve seat and opens the valve. When suction is not performed at the mouth, the shifted force at the valve closure site returns the valve closure site to the closed position, maintains the closure, and any positive pressure at the valve inlet increases the closing force. .

この種の弁は、ある要求に適合する必要性から、幼児向けに大量使用される液漏れ防止カップには適用されていない。特に、以下の全ての基準に適合することが重要である：
・全ての部位の全ての側面は十分な掃除のため接触可能であること
・ダイアフラムは、取り付け時に、大気に晒されるが、カップの外側から偶然であっても接触可能であってはならないこと
・分離された部位の数は最小にされ、その形は製造原価を最小化し、取扱いを容易にする形状にすること
・掃除のための分解は容易で再組立の方向は１方向のみで可能であること
・安全のため、特定の最小寸法より小さい寸法の部位を使用してはならないこと This type of valve has not been applied to leak-proof cups that are used in large quantities for infants because of the need to meet certain requirements. In particular, it is important to meet all the following criteria:
・ All sides of all parts must be accessible for thorough cleaning ・ Diaphragm is exposed to the atmosphere during installation, but it must not be accessible even by chance from the outside of the cup. The number of separated parts is minimized, its shape minimizes manufacturing costs, and makes it easy to handle.-Disassembly for cleaning is easy and reassembly is possible in only one direction. For safety reasons, do not use parts with dimensions smaller than the specified minimum dimension.

液漏れ防止カップ内でのデマンド弁の組み込みは、弁と飲み口との間の容積が最小に維持される必要があるという困難を伴う。この容積は、料飲後、液体に満たされ、そして結果的に液漏れし、あるいは横振りにより液漏れする。従来技術では小さな穴を間に挟むことが提案されてきたが、この方法はカップからの料飲をより困難にする。またそれは弁の部位の成形と掃除の容易さに対し逆効果となる。   Incorporating a demand valve in a leak proof cup involves the difficulty that the volume between the valve and the spout needs to be kept to a minimum. This volume fills with liquid after drinking and consequently leaks, or leaks due to sideways shaking. Although the prior art has suggested putting small holes in between, this method makes it more difficult to drink from a cup. It also has an adverse effect on the ease of shaping and cleaning the valve site.

特許文献４は本発明に最も近い従来技術であり、飲料が容器から１つの飲み口を経由して吸飲され、一方吸飲されない時は液漏れを防止する、飲料容器を閉鎖する蓋を開示している。デマンド弁は蓋に取り込まれ、デマンド弁は容器の内部に接続する１つの入口と、飲み口と接続する１つの排出口と、蓋内の１つの穴を経由して周辺大気と接続する１つの制御口を有する。弁は１つの弁シートと入口から排出口への流れを制御する１つの閉鎖要素を有し、その閉鎖要素は容器内の圧力により弁シートに対し密閉する方向に駆動され、また排出口と比較した制御口の圧力の余剰圧力に依存して、開放位置に駆動される。弁を開放する閉鎖要素の動きは、弁を通過する液流の向きと逆方向である。デマンド弁は、蓋の飲み口の中に組み込まれた２つの部位から形成される。第１の部位は剛性で弁の入口と弁シートを画定する。第２の部位は弁の閉鎖要素と圧力感応型ダイアフラムとして機能する１つの弾性膜からなり、第２の部位は第１の部位に対し、また蓋の穴の周りを密閉する。   Patent Document 4 is a prior art closest to the present invention, and discloses a lid that closes a beverage container that prevents the beverage from being leaked when the beverage is sucked from the container through one drinking mouth and not sucked. is doing. The demand valve is taken into the lid, and the demand valve is connected to the surrounding atmosphere via one inlet connected to the inside of the container, one outlet connected to the drinking mouth, and one hole in the lid. Has a control port. The valve has one valve seat and one closing element that controls the flow from the inlet to the outlet, which is driven in a sealing direction against the valve seat by the pressure in the container and compared to the outlet Depending on the surplus pressure of the control port pressure, it is driven to the open position. The movement of the closing element that opens the valve is opposite to the direction of the liquid flow through the valve. The demand valve is formed from two sites that are incorporated into the mouth of the lid. The first portion is rigid and defines a valve inlet and a valve seat. The second part consists of a valve closure element and a single elastic membrane that functions as a pressure sensitive diaphragm, the second part sealing against the first part and around the hole in the lid.

後者の特許仕様の液漏れ防止カップは満足に動作するようには作製されず、商品化されてはいない。その設計に固有の特性により、デマンド弁の第２の部位は第１の部位を信頼性を持って密閉できない。   The latter patented leak-proof cup is not made to operate satisfactorily and has not been commercialized. Due to the inherent characteristics of the design, the second part of the demand valve cannot reliably seal the first part.

（発明の目的）
そこで本発明は、デマンド弁を有し、そのデマンド弁の構成要素である剛性および弾性部位の間で信頼性のある密封がされる液漏れ防止カップ用の蓋を提供することを目的とする。 (Object of invention)
SUMMARY OF THE INVENTION An object of the present invention is to provide a lid for a liquid leakage prevention cup that has a demand valve and has a reliable seal between the rigid and elastic parts that are components of the demand valve.

本発明によれば、１つの液体飲料容器を密閉するための蓋（１０）であって、飲料が容器から飲み口（２０）を経由して吸飲されることを可能にし、一方吸飲が行われない時には液漏れを防止し、ここにおいて１つのデマンド弁（１６，１８）が蓋（１０）に組み込まれ、デマンド弁は、容器内部に接続する１つの入口（１８４、１８６）と、飲み口（２０）と接続する１つの排出口と、蓋内の１つの穴（１０１）を介して周辺大気と接続する１つの制御口を有し、弁は、１つの弁シート（１８４）と入口から排出口への流れを制御する１つの閉鎖要素（１６４）を備え、閉鎖要素（１６４）は容器内の圧力により弁シート（１８４）を密閉する方向に駆動され、また制御口の圧力の排出口の圧力に対する余剰分に依存して１つの開放位置に駆動され、閉鎖要素（１６４）の弁を開放する動きは弁を経由する液体の流れの方向と逆方向であり、ここにおいてデマンド弁は蓋の内側表面に搭載される２つの部位からなり、第１の部位（１８）は剛性で弁入口と弁シート（１８４）を画定し、第２の部位（１６）は弁閉鎖要素（１６４）と弁閉鎖要素に接続し圧力感応ダイアフラムとして機能する１つの弾性膜を含み、第２の部位（１６）は、第１の部位（１８）に対しまた蓋内の穴（１０１）の周囲を密閉し、第２の部位（１６）は第１の部位（１８）の全外縁を囲み、かつ密閉することを特徴とする蓋が提供される。     According to the present invention, a lid (10) for sealing one liquid beverage container, which allows a beverage to be sucked from the container via a drinking mouth (20), while drinking When not done, it prevents liquid leakage, where one demand valve (16, 18) is built into the lid (10), the demand valve has one inlet (184, 186) connected to the interior of the container, and a drink The outlet has one outlet connected to the mouth (20) and one control opening connected to the surrounding atmosphere via one hole (101) in the lid, the valve having one valve seat (184) and an inlet A closing element (164) for controlling the flow from the outlet to the outlet, the closing element (164) being driven in a direction to seal the valve seat (184) by the pressure in the container, One open position depending on the excess for the outlet pressure The movement of the closing element (164) to be opened is opposite to the direction of liquid flow through the valve, where the demand valve consists of two parts mounted on the inner surface of the lid, One part (18) is rigid and defines a valve inlet and a valve seat (184), and a second part (16) is connected to the valve closure element (164) and the valve closure element and functions as a pressure sensitive diaphragm. Including the elastic membrane, the second part (16) seals against the first part (18) and around the hole (101) in the lid, and the second part (16) is the first part ( A lid is provided that surrounds and seals the entire outer edge of 18).

特許文献４における弾性部位は、剛性部位の前面と後面の両方を密閉接触する必要がある。密閉接触線は一方の面の剛性部位の外部縁の一部にしか存在しない。接触線はさらに剛性部位の縁を横切り反対側に至る。実際には、このような密閉は、掃除のため分解されまた再組立されるように設計された弁では困難である（不可能ではないとしても）。   The elastic part in Patent Document 4 needs to make hermetic contact with both the front surface and the rear surface of the rigid part. The hermetic contact line exists only at a portion of the outer edge of the rigid portion of one side. The contact line further traverses the edge of the rigid part to the opposite side. In practice, such a seal is difficult (if not impossible) with valves designed to be disassembled and reassembled for cleaning.

本発明の好ましい実施形態では、弾性部位はまた飲み口の延長部を密閉する。
本発明の蓋は飲料カップの縁に適合するようにもともと意図されているが、それはあるいはボトルやプラスチック・バッグに適合してもよい。さらに、第１と第２の部位が掃除と殺菌のため蓋から分離可能で、蓋と飲料容器を再使用可能とすることは重要な利点であるが、あるいは蓋は使い捨て容器の一部を構成してもよく、そのような用途では第１と第２の部位が蓋から分離可能である必要はない。
好適には、第２の部位は蓋と第１の部位の間に捕捉される。 In a preferred embodiment of the invention, the elastic site also seals the extension of the drinking mouth.
The lid of the present invention is originally intended to fit the edge of a beverage cup, but it may alternatively fit a bottle or plastic bag. Furthermore, it is an important advantage that the first and second parts can be separated from the lid for cleaning and sterilization, and that the lid and beverage container can be reused, or the lid constitutes part of the disposable container In such applications, the first and second sites need not be separable from the lid.
Preferably, the second part is captured between the lid and the first part.

好適には偏在手段が閉鎖要素を閉鎖位置に駆動するのに用いられる。一度閉鎖要素が弁シートと接触すると、どの方向に対しても弁が閉鎖を維持するために、偏在力が残存している必要は無い。何故ならば、容器が逆さにまたは一部逆さになり、容器の液体が排出される可能性がある場合にのみ、弁は閉鎖される必要があり、そのような場合は弁シートと閉鎖要素との間に働く液体の表面張力が弁の閉鎖を維持するからである。一度カップの液体が閉鎖要素のところで滞留すると、本質的に静止した状態または緩慢な運動においては閉鎖を維持するのに他の力は必要ない。逆さまたは一部逆さになったカップが激しい横運動にさらされた場合のため、非常に小さな偏在力を加えておくことが望ましい。   Preferably uneven distribution means are used to drive the closure element to the closed position. Once the closure element comes into contact with the valve seat, there is no need to have an uneven force remaining in order for the valve to remain closed in any direction. This is because the valve needs to be closed only when the container is upside down or partly upside down and the liquid in the container can be drained, in which case the valve seat and the closure element This is because the surface tension of the liquid working during the period maintains the valve closed. Once the cup liquid has accumulated at the closure element, no other force is required to maintain the closure in an essentially stationary state or in slow motion. It is desirable to apply a very small uneven force for cases where an inverted or partially inverted cup is subjected to intense lateral movement.

弁シートと排出口との間の容積は最小でなければならず、従ってダイアフラムと第１の部位との間の空間は最小化されなければならない。ダイアフラムが飲み口からの吸い込みにより第１部位の方向に引き込まれるので、この空間はダイアフラムの動作を調節する必要がある。その時ダイアフラムは一般的には浅いお椀状に変形される。ダイアフラムを引張する正味の力は、ダイアフラムの直径と弁シートの直径（後者は適正な流れを可能にするため十分に大きくなければならない）との間の環状部分にのみ働く吸引力によりもたらされる。従って第１部位の形状は、第１部位とダイアフラムとの間で環状部分に捕捉された液体、および表面張力が吸飲を受ける実効正味面積を更に減少させないような形状でなければならない。その目的のため、一般的には円錐形に凹んだ第１部位の上部表面は、表面が僅かに薄い縁より凹むように、急な傾斜のリップをその縁周囲に備えている。   The volume between the valve seat and the outlet must be minimal, so the space between the diaphragm and the first site must be minimized. Since the diaphragm is drawn in the direction of the first part by suction from the drinking mouth, this space needs to adjust the operation of the diaphragm. At that time, the diaphragm is generally deformed into a shallow bowl shape. The net force pulling the diaphragm is provided by the suction force acting only on the annulus between the diaphragm diameter and the valve seat diameter (the latter must be large enough to allow proper flow). Accordingly, the shape of the first portion must be such that the liquid trapped in the annular portion between the first portion and the diaphragm and the surface tension does not further reduce the effective net area that is swallowed. For that purpose, the upper surface of the first section, generally concave in a conical shape, is provided with a steeply sloped lip around its edge so that the surface is recessed from a slightly thinner edge.

部位１６は弾性材料から作られ、一方部位１８と蓋１０は、その中に柔らかいまたは弾性の部分を含むが、剛性である。３つの部位１０，１６，１８が容易に識別できるように図１では弾性部位１６のみ斜線が施されている。弁の３つの部位は掃除が可能なように互いに分離可能で、また弾性部位１６を最初に剛性部位１８に適合させ、しかる後２つの部位１６，１８を一緒に蓋の溝１４に挿入することにより組立可能である。剛性部位１８と蓋との間における弾性部位１６の縁の圧縮力により弾性部位１６と剛性部位１８は溝１４の中に保持される。同時に、密閉リング１６３が飲み口延長部２０１とチャンバ１８１との間の圧縮力により保持される。   Region 16 is made of an elastic material, while region 18 and lid 10 include a soft or elastic portion therein but are rigid. In FIG. 1, only the elastic portion 16 is hatched so that the three portions 10, 16, 18 can be easily identified. The three parts of the valve are separable from each other so that they can be cleaned, and the elastic part 16 is first adapted to the rigid part 18 and then the two parts 16, 18 are inserted together in the lid groove 14 Can be assembled. The elastic part 16 and the rigid part 18 are held in the groove 14 by the compressive force of the edge of the elastic part 16 between the rigid part 18 and the lid. At the same time, the sealing ring 163 is held by the compressive force between the drinking mouth extension 201 and the chamber 181.

図３に示すとおり、剛性部位１８は１つの通路１８３により接続される、２つのチャンバ１８１，１８２を画定する。
弁の組立後チャンバ１８１は飲み口２０と密閉されて連結し、チャンバ１８２は全体的に漏斗型で弁シート１８４に囲まれる開口部１８６を介してカップ内部と連結している。通路１８３は、チャンバ１８２の圧力が飲み口２０での吸い込みにより減圧されることを可能にし、またカップから液体が飲み口２０に流れることを可能にする。
円柱型に曲がったハンドル１８５は部位１８の下方から片手を伸ばして親指と人差指の間で簡単につまめる。これにより部位１８は、弾性部位１６がその上に取り付けられる間も、あるいはそこから外される間も、保持され、さらに剛性部位１８が蓋１０の溝１４に押し込まれ、あるいは押し出されることを可能にする。 As shown in FIG. 3, the rigid portion 18 defines two chambers 181 and 182 connected by one passage 183.
After the assembly of the valve, the chamber 181 is sealed and connected to the drinking mouth 20, and the chamber 182 is connected to the inside of the cup through an opening 186 surrounded by the valve seat 184 as a whole in a funnel shape. The passage 183 allows the pressure in the chamber 182 to be reduced by suction at the spout 20 and allows liquid to flow from the cup to the spout 20.
The handle 185 bent in a columnar shape can be easily pinched between the thumb and index finger by extending one hand from below the region 18. This allows the part 18 to be retained while the elastic part 16 is attached or removed from it, and further allows the rigid part 18 to be pushed or pushed into the groove 14 of the lid 10. To.

弾性部位１６は、剛性部位１８の縁の全周を囲む、下方に向いた縁１６１を有する。この構成により、弾性部位１６と剛性部位１８の効果的密閉が実現される。
弾性部位１６は、縁１６１に囲まれた領域の中に、下方に突出した密閉リング１６３に囲まれた１つの孔１６２を有し、密閉リング１６３は、短く内側に突出する管状の飲み口延長部２０１を取り囲み密閉する。デマンド弁の組立後、密閉リング１６３はチャンバ１８１内に配置され、チャンバ１８１の内壁と管状の飲み口延長部２０１との間に押し付けられ密閉を実現し、これにより飲み口２０と弾性部位１６の下方の面（図１の方向で見て）のみとの間での液体の交通が可能となる。 The elastic part 16 has a downwardly facing edge 161 that surrounds the entire circumference of the edge of the rigid part 18. With this configuration, effective sealing of the elastic portion 16 and the rigid portion 18 is realized.
The elastic part 16 has a hole 162 surrounded by a sealing ring 163 projecting downward in a region surrounded by the edge 161, and the sealing ring 163 is a tubular drinking mouth extension projecting short and inward. The part 201 is surrounded and sealed. After the demand valve is assembled, the sealing ring 163 is disposed in the chamber 181 and is pressed between the inner wall of the chamber 181 and the tubular drinking mouth extension 201 to realize the sealing, whereby the drinking mouth 20 and the elastic portion 16 are sealed. Liquid traffic between only the lower surface (seen in the direction of FIG. 1) is possible.

弾性部位１６はまた下方に突出したきのこ型の１つの弁閉鎖部位１６４を有し、その寸法は剛性部位１８の開口部１８６を押し通らされ、また、引き出されることが出来るような寸法になっている。その弾性のため、剛性部位のチャンバ１８２の上方に位置する部位１８の領域は１つのダイアフラムの働きをし、閉鎖部位上で引きあがり、開口部１８６を囲む弁シート１８４と密閉接触を維持する。
１つの小さな開口部１０１がダイアフラムの上方の蓋に設けられ、大気圧が弾性部位１６の上面に作用するようになっている。 The resilient portion 16 also has a single mushroom-shaped valve closure portion 164 that projects downwardly, dimensioned so that it can be pushed through the opening 186 of the rigid portion 18 and pulled out. Yes. Because of its elasticity, the region of the region 18 located above the rigid region chamber 182 acts as a diaphragm, pulls up on the closed site, and maintains hermetic contact with the valve seat 184 surrounding the opening 186.
One small opening 101 is provided in the lid above the diaphragm so that atmospheric pressure acts on the upper surface of the elastic portion 16.

液体が飲み口２０より吸われてカップ内に真空が生ずるのを防ぐため、空気がカップ内に進入することを可能にする換気装置が必要となる。もちろんこの換気の間に液体がカップより漏れることは許されず、この理由により、１つの1方向弁を使用することが一般的である。このような弁の既知の形は括約筋弁であり、それは、１つ以上のスリットにより２つ以上の薄板に分割された１つの凸型弾性表面からなり、その薄板は分離して１方向への空気の流れを可能にし、一方で圧搾されて互いに密閉し逆方向への液体の流れを防止する。   In order to prevent liquid from being sucked in from the spout 20 and creating a vacuum in the cup, a ventilator that allows air to enter the cup is required. Of course, no liquid is allowed to leak from the cup during this ventilation, and for this reason it is common to use one one-way valve. A known form of such a valve is a sphincter valve, which consists of one convex elastic surface divided into two or more lamellae by one or more slits, which lamellas separate into one direction. Allow air flow while being squeezed to seal each other and prevent liquid flow in the opposite direction.

図２はこのような括約筋弁が側面に伸長する腕部１６７の端で弾性部位と統合されて形成されるさまを示す図である。弁１６６は蓋からカップの内部に突出する短い管に適合する。しかしその管も括約筋弁１６６も図１の断面図には表示されていない。
使用されないとき、デマンド弁の各部位は図１に示す配置をとる。即ち、きのこ型弾性部位１６の頭部は弁シート１８４に対し密閉し、液体がカップの内側から飲み口２０を経由して漏れるのを防止する。弁シート１８４は平面ではなく、頭頂点が下方を向くわずかに円錐形をしており、これにより閉鎖部位１６４と弁シート１８４とが線接触を実現している。弁シートの周りの密閉を向上させる以外に、この頭頂点の形状はベンチュリ（ベルヌーイ）効果を低減する。この時に、弾性部位１６のダイアフラム部分は完全に弛緩した状態にあってよい、あるいは僅かに弛緩状態から外れて弾性偏在力を閉鎖部位１６４にかけてもよい。 FIG. 2 is a view showing such a sphincter valve formed by being integrated with an elastic portion at an end of an arm portion 167 extending to the side surface. Valve 166 fits a short tube that protrudes from the lid into the cup. However, neither the tube nor the sphincter valve 166 is shown in the cross-sectional view of FIG.
When not in use, each part of the demand valve takes the arrangement shown in FIG. That is, the head of the mushroom-shaped elastic part 16 is sealed against the valve seat 184 to prevent liquid from leaking from the inside of the cup via the drinking mouth 20. The valve seat 184 is not a flat surface, but has a slightly conical shape with the head apex facing downward, so that the closed portion 164 and the valve seat 184 are in line contact. In addition to improving the seal around the valve seat, the shape of the head apex reduces the Venturi effect. At this time, the diaphragm portion of the elastic portion 16 may be in a completely relaxed state, or may be slightly out of the relaxed state and apply an elastic uneven force to the closed portion 164.

カップが逆さにされた場合、頭部弁閉鎖部位１６４にかかる圧力は弁閉鎖部位をより強く弁シートに押し付け、この効果は閉鎖部位１６４と円錐形弁シート１８４との間の表面張力によりさらに助長される。従って密閉はカップの逆転のみならず、横ぶれや、炭酸飲料や温飲料で起こりうるカップ内の高圧蓄積にも耐えることが可能である。
弁が使用されていないときに、弁閉鎖部位１６４と弁シート１８４との間の密閉を保つため弾性部位１６の自然弾性が必要に応じて付加され、あるいは磁気により補助される。例えば、弾性部位１６は磁気または鉄の粉を含む材料で作られ、カップ１０または第１部位に磁石が埋め込まれる。他の形の偏在方法が選択肢として可能である。例えばバネが使用可能で、これらのバネは第１部位または第２部位に埋め込み成形可能である。またさらに第１部位の上部表面に直線、曲線または角度のついた弾性の「ひれ」を設けることも可能である。あるいは、第２部位の内部面に直線、曲線または角度のついた下方に突き出た弾性の「ひれ」を設けることも可能である。 When the cup is inverted, the pressure on the head valve closure site 164 pushes the valve closure site more strongly against the valve seat, and this effect is further enhanced by the surface tension between the closure site 164 and the conical valve seat 184. Is done. Therefore, the sealing can withstand not only the reversal of the cup but also the high-pressure buildup in the cup that can occur with a side shake or a carbonated drink or a hot drink.
When the valve is not in use, the natural elasticity of the elastic portion 16 is added as needed or magnetically assisted to maintain a seal between the valve closing portion 164 and the valve seat 184. For example, the elastic portion 16 is made of a material containing magnetic or iron powder, and a magnet is embedded in the cup 10 or the first portion. Other forms of uneven distribution are possible options. For example, springs can be used and these springs can be molded in the first part or the second part. Furthermore, it is also possible to provide an elastic “fin” with a straight line, a curve or an angle on the upper surface of the first part. Alternatively, it is also possible to provide an elastic “fin” protruding downward with a straight line, a curve or an angle on the inner surface of the second part.

カップの使用中、使用者は飲み口２０で吸飲し、これがチャンバ１８１内部の圧力を大気圧以下に下げる。この減圧は通路１８３を通じてチャンバ１８２の上方に位置する弾性部位１６の部分に伝えられ、１つのダイアフラムとして機能する。ダイアフラムの反対側の気圧は開口部１０１により大気圧に保たれているため、正味圧力が弁閉鎖部位１６４に弁シート１８４から離れる方向に働き、これにより液体が、今や逆さにされたカップから第１にチャンバ１８２に流れ、次に通路１８３を通ってチャンバ１８１に流れ、飲み口２０からカップ外に吸い出されることを可能にする。液体に接触する弁閉鎖部位１６４の小さな面積に比較して低圧に晒されたダイアフラムが広い面積を有するため、弁を開けるための飲み口での吸い込み圧は大きい必要はない。   During use of the cup, the user sucks at the drinking mouth 20, which lowers the pressure inside the chamber 181 to below atmospheric pressure. This reduced pressure is transmitted to the portion of the elastic portion 16 located above the chamber 182 through the passage 183, and functions as one diaphragm. Since the air pressure on the opposite side of the diaphragm is maintained at atmospheric pressure by the opening 101, the net pressure acts in the direction away from the valve seat 184 at the valve closure site 164, so that the liquid is now removed from the inverted cup. 1 flows into the chamber 182 and then through the passage 183 to the chamber 181, allowing it to be sucked out of the cup 20 from the spout 20. Since the diaphragm exposed to low pressure has a large area compared to the small area of the valve closing part 164 in contact with the liquid, the suction pressure at the mouth for opening the valve need not be large.

液体が飲み口より吸われるに従い、空気が換気括約筋弁１６６を通って流入し、カップからの料飲が加速的に困難にはならない。
従って、デマンド弁は、弁シートからなる吸引口と、飲み口と繋がる排出口と、液体容器の内部から独立し蓋の開口部１０１を通じて周辺大気と連結する制御口と、を有し、弁は排出口と制御口との差圧により開かれると見ることも出来る。
上記に記載された設計の種々の詳細についての重要性は十分に評価されるべきであることを特記しておく。
デマンド弁を開けるためには、閉鎖部位１６４が液体の流れと逆方向に移動されなければならない。従って弁はカップ内の圧力では開けることは出来ず、飲み口の吸引によってのみ開けられる。
カップ内の圧力は弾性ダイアフラムの上部面とは連結せず換気用開口部１０１を通じての圧力漏れは起こらない。 As liquid is sucked from the mouth, air flows through the ventilated sphincter valve 166, and drinking from the cup does not become difficult at an accelerated rate.
Therefore, the demand valve has a suction port made of a valve seat, a discharge port connected to the drinking port, and a control port that is independent from the inside of the liquid container and is connected to the surrounding atmosphere through the opening 101 of the lid. It can be seen that it is opened by the pressure difference between the discharge port and the control port.
It should be noted that the importance of the various details of the design described above should be fully appreciated.
In order to open the demand valve, the closure site 164 must be moved in the opposite direction of the liquid flow. Therefore, the valve cannot be opened by the pressure in the cup, and can only be opened by sucking the mouthpiece.
The pressure in the cup is not connected to the upper surface of the elastic diaphragm, and no pressure leaks through the ventilation opening 101.

後者の開口部１０１は小さくダイアフラムはカップの外部から接触することはできない。ダイアフラムが物理的にカップの外側から押し潰されれば、ダイアフラム全体が大気に暴露され圧力漏れが発生する。本発明のこの実施形態ではこの状態は細い物体を開口部１０１から慎重に突いた場合にのみ起こる。
弁の各部位は、掃除や消毒に重要である、分解が出来ること以外に、各部位は不正確に再組立が出来ないようになっている。全ての部位の左右対称な楕円形の周囲の形により、１つの方向でのみ互いに適合することが保証されている。
使い捨て容器の蓋として使用する場合は、各部位は分解可能である必要は無く、どのような形の接着によっても組み立てられうる。
カップの全ての部品は「小部品」規制に適合する程度に、十分大きい寸法である。 The latter opening 101 is small and the diaphragm cannot contact from the outside of the cup. If the diaphragm is physically crushed from the outside of the cup, the entire diaphragm is exposed to the atmosphere and a pressure leak occurs. In this embodiment of the invention, this condition only occurs when a thin object is carefully struck from the opening 101.
Each part of the valve is not capable of being reassembled inaccurately other than being disassembling, which is important for cleaning and disinfection. The symmetrical perimeter shape of all parts ensures that they fit each other in only one direction.
When used as a lid for a disposable container, each part need not be disassembled and can be assembled by any form of adhesion.
All parts of the cup are sufficiently large to meet the “small parts” regulations.

使用者が飲み口での料飲を終えた時に、幾らかの量の液体が、飲み口、チャンバ１８２および通路１８３に残されている。飲み口は、液体がそこから出て行く時には同時には空気は下方に入り込めないように寸法を決められているため、液体が漏れることはない。
それでも横に振ればこの体積の液体は漏れ出す可能があり、上記の設計の中で重要な点は、「小部品」規制に適合する部位を使用しても弁シートより下流の液体体積は３ｍｌより少なく維持することと、弁シートと飲み口の間の通路のいずれにおいても断面積が０．９平方ミリより小さい場所が無いことである。 Some amount of liquid is left in the spout, chamber 182 and passage 183 when the user finishes drinking at the spout. The mouthpiece is dimensioned so that air cannot enter the lower part at the same time as the liquid leaves, so no liquid will leak.
Still, this volume of liquid can leak if shaken sideways, and the important point in the above design is that the volume of liquid downstream of the valve seat is 3 ml even if a site that meets the “small parts” regulations is used. Less and there is no place where the cross-sectional area is less than 0.9 square millimeters in any of the passages between the valve seat and the mouthpiece.

剛性部位１８の漏斗型上部表面には急な角度で傾斜したリップがその周辺部に備わっていて、剛性部位がダイアフラムの下部へ接近することを制限している。これは２つの間の接触を防止すると共に２つの間に捕捉された薄い液体の層による表面張力効果を防止するためであり、これら２つの現象は吸引を受けるダイアフラムの実行面積を大幅に減少させる。
本発明の好ましい実施形態によれば、蓋以外に２つだけの部品を使用する。これは掃除を単純化するだけでなく、製造原価を最小にする。
さらにこの観点から、３つの部位のそれぞれは２部位の鋳型で成形でき、高価な製造機械が不要な点が指摘される。 The funnel-shaped upper surface of the rigid portion 18 is provided with a lip inclined at a steep angle at the periphery thereof to restrict the rigid portion from approaching the lower portion of the diaphragm. This is to prevent contact between the two and to prevent surface tension effects due to the thin liquid layer trapped between the two, these two phenomena significantly reducing the effective area of the diaphragm under suction. .
According to a preferred embodiment of the invention, only two parts are used besides the lid. This not only simplifies cleaning, but also minimizes manufacturing costs.
Furthermore, from this point of view, it is pointed out that each of the three parts can be molded with two parts of the mold, and an expensive manufacturing machine is unnecessary.

本発明の他の実施形態によれば、蓋の開口部１０１はダイアフラムの逆側と同一平面にはない。そのかわり蓋は周辺大気に接続する穴を１つの換気穴により画定する。ダイアフラムの逆側を周辺大気と換気する他、その穴は、前記の括約筋弁１６６に類似した１つの弁を経由して、飲料カップの内部を換気する機能を果たす。   According to another embodiment of the present invention, the lid opening 101 is not flush with the opposite side of the diaphragm. Instead, the lid defines a hole that connects to the surrounding atmosphere with a single ventilation hole. In addition to venting the other side of the diaphragm to the surrounding atmosphere, the hole serves to vent the interior of the beverage cup via a single valve similar to the sphincter valve 166 described above.

本発明はカップでの使用に限定されず、ボトル用蓋あるいは柔軟壁の容器においても使用可能であることが明確にされなければならない。さらに、蓋は容器から分離可能である必要は無く、恒久的に一体化されて容器全体を使い捨て用にすることもできる。さらに飲み口部分は柔軟でストローのような伸長された延長部を有してもよい。   It should be clarified that the invention is not limited to use in cups but can also be used in bottle lids or flexible wall containers. Furthermore, the lid need not be separable from the container, but can be permanently integrated to make the entire container disposable. In addition, the spout portion may be flexible and have an elongated extension such as a straw.
